Configuring and Backing Up Permanent Connections • Chapter 7 293
In the case of Cisco routers with an AIP ATM interface, the PVCs are
mapped point-to-point, or point-to-multipoint.
Configuring ATM
Configuring routers for ATM is similar to any other interface on Cisco
routers. Set up the interface subsystem in the configuration mode, by
typing the interface-related detailed syntax. Figure 7.19 illustrates how to
build an ATM network; configurations follow in Figures 7.20 and 7.21.
